I was able to boot both 5420 and 5800 with just the arch timers on our
3.8 based franken-kernel.  The upstream kernel doesn't boot on those
systems with or without the mct so I wasn't able to test there.
Although looking at the upstream device tree now I see that there is
no entry for the arch timer in exynos5420.dtsi.  Maybe it should be
added in?
